I am running the editor on a Windows 10 system.
When I type a name into the position 1 box and save it everything is OK.
When I type a \n message to go to another line and save the preset everything again is OK
However when I go to the next preset or even the first one which was OK the display is corrupted by the 2nd line stuff. This even extends across new or existing banks.
The only way I have found to correct it temporarily is by going into (see above image with EMPTY) and typing \n after EMPTY or the name that is there and then backspacing the \n out and that clears it.
